PROCESS OF MAKING WIRE-GLASS. v

Application filed June 26, 1915.

To all whom it may concern:

Be it known that I, NICKLAS FRANZEN, a citizen of the United States, residing at Port Allegany, in the county of McKean and State of Pennsylvania, have invented certain new and useful Improvements in Processes of Making Wire-Glass, of which the following is a full, clear, and exact description.

My invention relates to improvements in processes of making wire glass, and particularly to.that process comlmonly designated as the single pour process, which consists, generally speaking, of dumping a single pour or ladle of glass upon the table, smoothing out the same into a flat sheet by a forward roll spaced from the bed of the table a distance equal to the thickness of the desired sheet, introducing wire into the sheet While still soft, by a corrugated roll situated behind the front or sheet forming roll, and moved progressively forward as the front roll advances, and then utilizing'a smoothing roller advancing in the rear of the corrugated roller, in an attempt to cover up the irregularities or indentations of the sheet of glass Which have been made by the Wire forced into it. Such a process is disclosed,

"together with appropriate apparatus for carrying it into effect, in United States patents to Frank Shuman, Nos. 483,020 and 483,021. One great objection to this method has always been the scarifying of the upper surface of the glass sheet, due to the introduction of the wire, which the rear, of smoothing roller cannot fully obliterate by any of the means heretofore used or known,

although many expedients have been devised and applied in efforts to eradicate the defects. My present improvement is designed to avoid this objection to the single pour process, and it consists of an improvement inthe Shuman process, comprising, generally speaking, the formation of a wave or crest iii the sheet at the head end, justahead of the point where the Wire is first fed into the glass, and pushing this crest or wave forward by the smoothing roll after the introduction of the wire, thus utilizing the surplus of glass so formed to obliterate the scarifications left by the corrugations of the wire impressing roll and by the introduction of the wire itself.

In cafrying out my invention, I prefer to Specification of Letters Patent.

Patented Sept. 26, 1916.

Serial No. 36,426. I

use mechanism such as shown in the accompanying drawings.

Figure 1 is a diagrammatic view of the table and some of its accessories, together with the forming rolls. Fig. 2 is a plan view, and Fig. 3 is a longitudinal section at an advanced stage of the wire-glass forming process.

In the drawings, I represents the table bed.

A is the front or forming roll.

B is the corrugated roll for introducing the wire to the glass.

C is the rear-or smoothing roll.

I) represents the wire fed down to the glass, as by a chute I).

Near the front or head end of the table, I provide on either side a cam or slightly elevated surface G, so arranged as to be in registry with the collars I-I, upon the front roll A; whereas the collars II on the corrugated roll B and upon the rear orsmoothing roll C, having less lateral extension than those of the front i'oll, pass between the cams (ir as the rollstravel over the table.

In the actual construction of the parts,

the table I may be so mounted and arranged the table may be fixedly mounted and the rolls arranged to travel baclnvardly and forwardly across its surface. Both of these arrangements are Well known and of com mon application in this art, and my invention may be applied to either. For convenience, I have illustrated a construction in which the table bed isstationary and the rolls are caused to move across its surface.

In carrying out my process, a ball of glass is cast upon the table at its head end and the rolls arestarted forward, that is, to the right as shown in the drawing. As the front roll A reaches the cast of glass, it proceeds to roll and smooth oifa flat sheet whose thickness is determined by the thick- 'ness of thecollars H upon the rolls. When the roll H encounters the cam surfaces G, it rides up upon them, so as to leave a Wave or ridge of glass, as at F, due to the inface and completes the rolling of the glass sheet, the wire D being fed down the chute E and into the glass beneath the corrugated roll B. This process scarifies the upper surface of the glass sheet, as hereinbefore described. The smoothing roll C, following after roll B and at substantially the same height from the table as the forming roll A, pushes the' wave F of glass in front of it, thereby closing up and obliterating the scars in the surface of the glass. When the rolls in the order named have proceeded over the entire length of the table, the glass sheet is removed and carried to the leer in the ordinary manner.

It will be readily understood that changes may be made in the details of the mechanism, for my process is susceptible of utilization in a variety of apparatus.

What I claim as my invention is:

The process of manufacturing Wire glass, which consists in forming a ball or batch of molten glass into a smooth flat sheet having a ridge or Wave on its surface at the head end of the sheet, introducing a Wire fabric into the glass sheet through the upper surface thereof, and pushing the Wave or ridge on the surface of the sheet progressively forward over the part containing the wire fabric, so as to close up and smooth out the irregularities upon the surface of the glass caused by forcing the fabric into the sheet. In testimony whereof I afiix my signature in the presence of two subscribing Witnesses.
